To all whom it may concern.:

Be it known that I, DANIEL li. Powuas, a citizen of the llnited States, residing at Arvada.l the county of Jefferson and State of Colorado, have' invented certain new and useful Improvements in Spring Lubricators; and l do declare the following to be a full, cleaigand exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of ref# erence marked thereon, which. form part of this specification. y y

This invention relates to a device adapted to be attached to an ordinary spring for the purpose of facilitating the proper lubrication thereof.

Springs, such as are ordinarily employed for supporting the bodies of vehicles, more especially those employed in connection with automobiles, are, almost withoutexcep tion, formed from a plurality of leaves which are assembled so as to form a spring of sufficient strength. The proper functioning of a spring of the multiple leaf type re quires that the leaves shall be free to slide on one another, as only by so doing can the maximum amount of resiliency be obtained. The springs of an automobile are, as a rule, exposed to the effect of rain from above and also to the splashings of mud and water from below, with the result that water finds its way between the leaves of the springs and tends to make the adjacent surfaces rusty. `When the springs rust, in the manner suggested, the leaves will no longer slide as re' quired and the spring functions like a solid bar and not as a laminated structure.

It is usually difficult to lubricate a multiple leaf spring and they are therefore as a rule left unlubricated.

It is the object of this invention to provide a simple and inexpensive device that can be readily attached to any multiple leaf spring and which shall be so constructed and designed that it will permit oil to be constantly held against the side of the springs so that it may penetrate, by the help of capillary action, to the spaces between the adjacent surfaces and keep them properly lubricated. c n

ln order to more clearly describe my in` vention, l yshall have reference'to they accompanying drawing, in which- Fig. l is a side elevation of( aportion offa laminated spring and'shows my improved lubricator in place thereon. y f

The same reference numbers will be used to designate the same parts throughout the several Views.

Numeral ldesignates, as a Whole, a mult-is ple leaf spring of ordinary construction, and 2 designates the various leaves of which the spring is composed.` My improved lubricator,'which l have designated as a whole by numeral 3, consists yof two similarly constructed complementary members 4 and 5, each of which is provided at one end with the direction of two upwardly projecting, perforated ears 6,

tries., l

channel within'which the partl 5 slides in a manner clearly apparent fromthe drawings. The parts 4 and 5 have downwardly extending end flanges 10 whose inner edges are curved somewhat in the manner indicated i by numeral 1l so that as the bolt 8 is rotated, the lubricator will be firmly clampedv to the top leaf of the spring. Extending downwardly from the ends 10 are semicylindrical extensions l2 whose lowerL ends are closed, as indicated by numeral 18. The cylindrical extensionsv12 are filled with an absorbent material 14. which contacts the edges of the leaves of the' spring in the manner apparent from an inspection of Figs. 2 and 5. Holes l5 are -provided in members' 4 and 5 in the manner shown in Figs. 2 and 3.

g 10oy n My improved lubricator is clamped onto the spring in the manner apparent from the above description and from the drawing. Oil is then introduced through holes 15in sufficient quantity to saturate the absorbent material lll.A AAs the spring functions, oil will pass from the Wicks 14 into the spaces between the lea-ves and keep the surfaces thereof properly lubricated.

From the above it Will appear that l have invented a spring lubricator that can be cheaply made and readily applied to the springs and which has a large capacity 'for' oil and which Will automatically supply the needed lubrication to the spring.

Having non' described my invention, what I claim is:

l. A spring lubricator comprising, in combination. tivo relatively movable members, each having tivo portions angularly related to each other, one of said portions being conca'ije and adapted to fit'against the side of "a multiple leaf spring, the other por tion of one yof said members being` flat and `adapted to fit against the top of a sprino,

the corresponding portion of the other member being channel shaped and adapted to receive the fiat portion of the other member in adjustable relation, upwardly extending ears at the corners of each member and a clamping bolt passing` through said ears` and adapted to perform both the clamping and adjusting functions.

2'. A. spring lubricator comprising, in

`Combination,l two relatively movable members, each having a side portion and a top portion, said portions forming substantially a right angle With each other, the side portions being concave. and adapted to receive `and hold a piece of absorbent felt against the sides of a multiple leaf spring, the top portions of one of said members being flat and adapted to rest on the uppermost leaf of a multiple leaf spring, the top portion of the other member being channel shaped and adapted to receive the flat portion of the opposing member 'in adjustable relation, per-v forated ears extending upwardly above the top portions of each member and an adjusting holt projecting through said ears
